Application filed Hovemher 28, 1908. I Serial No. 464,868.

To all whom "it may concern:

Be it known that I, CHARLEY A. Do'rson, acitizen of the United States,residing at Huntington, in the county of Cabell and- State ofVVestVirginia, have invented certain new and useful lmprovements inLubricators; and I do hereby declare the follow.- ing to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to new and useful improvements in lubricators andmore "particularly to that class adapted to be used for lubricating thejournals of railway trucks and my object is to provide a retaining meansfor the lubricant, whereby Waste or the like usually employed forretaining the lubricant may be dispensed with.

A. furtheuobject is to provide means for holding the lubricator in engaement with the bearing parts of the journa A further object is toprovide means for gradually feeding the lubricant into engagement withthe journal.

A. still furtherobject is to provide means for compressing the parts ofthe lubricantholding device, whereby the same maybe introduced into orremoved from engage;

ment with the journal and a still further object is to provide means forholding the parts of the lubricator against casual disengagement witheach other.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claim. a

In the accompanying drawings which are made a part of this a plication,Figure 1 is an elevation of the hearing end of a car axle showing theusual form of housing and my improved lubricating device in section, andFig. 2 is a transverse sectional view as seen on line 22, Fig. 1.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indicate:: the usualor any preferred form of car axle, the bearing end 2 of which isprovided with an annular channel 3, the end walls of the channel 3forming shoulders 4 and 5 at the inner and outer ends, respectively, ofthe channel.

Surrounding the bearing end 2 of the axle is the usual or any preferredform of housing 6, to which is secured the usual form Specification ofLetters Patent.

of car body-supporting frame 7 and in order to provide a frictionalbearing surface between the housing and the axle, a bushing or hearingblock 8 is introduced between the upper portion of the housing and thebearing end 2 of the axle.

in order to maintain a lubricant and gradually feed the same intoengagement. with the frictional surface of the axle 1 and at the sometime dispense with waste, or the like, commonly em 'loyed for absorbingand retaining the ln ricant in the housing, I have provided my improvedform of lubricator which is preferably formed of metal and made in twosections 9 and 10, the section 9 resting upon the base of the housing 6,while the section 10 is of suflicient size to telescope around thesection S) and. has its upper wall 11 curved to fit the contour of thebearing surface of the channel 3. The upper section 10 is adapted toreceive and maintain the lubrica'nt and as the lubricant is preferablyreduced to a soluble state, it may be readily introduced into thesection 10 and gradually fed into engagement with the surface of thechannel 3 through plurality of slits 12 formed in the curved upperwall11. The lubricant is gradually fed through the slits 12 by means of aplunger 13, which plunger is introduced into the open end of the section10 after the lubricant has been placed therein and directs pressureagainst the lubricant by introducing springs 14; between the floor ofthe section 9 and the lower face of the plunger 13, said springs beingheld in proper alinement by means of lugs 15 and 16, on the section 9and plunger .13, respectively, and as the lubricant is consumed by theaxle, the pressure of the sprin s will gradually force a new supply ofthe ubricant through the. slits 12 and into engagement with thefrictional surface of the channel 3, thereby keepin a constant supply oflubricant on he and at the same time limiting the supply to such anextent as to prevent wast age of the lubricant.

The sections 9 and 10 are held in telescopic relation with each other bymeans of pins 17 which are introduced through the overlapping-endmembers of the two sections, the end members of the section 10 havingelon gated slots 18 therein to receive the pins, whereby the section 10will be permitted to telescope with the section 9 and in introduc ingthe lubrioator' position below the bear- 'ing end of the axle, thesection 10 is lowered a sullicient distance to permit the lubricator topass between the base of the housing 6 and the shoulder at the outerend. of thechannel 3 and as soon as the lubricator has been movedinwardly a sufficient distance,

-' the tension of the springs 14 will move the curved upper wall ll intoengagement with the frictional surface of the channel 3, the shoulders 4and 5 preventing undue longitudinal movement of the lubricator after thesame is properly positioned.

In removing the lubricator from the housin 6, the forward end of thesection 10 1s sulficie'ntly depressed to permit the lubricator to passthe shoulder 5 and in order to readily accomplish this result, I providealining ears 19 and 20 on the front end walls of the sections 9 and 10and by graspin said ears and moving the ear 20 toward the. car 19, theforward end of the section 10"will be lowered a suilicient distance topermit the same to clear the shoulder 5 when the lubricutor is movedoutwardly.

In introducing the lubricant into the section 10, the pins 17 areremoved and the section 10 elevated from engagement with the section 9when the plunger 13 is removed from the section 10 and the lubricantdeposited on the curved upper wall ll. The plunger 13 is then againintroduced into the section 10 and the section 10 placed in positionover the section 9, when the pins are again introduced into position andthe seetions 9 and 10 held in coiiperative relation-- ship witheachiother In view of the simplicity of my improved lubricator, the samemay be readily and cheaply constructed and used in connection with anysuitable form of bearing surface,

but particularly in connection with car axles and it will likewise beseen that the lubricant will be positively supplied to the bearingportion of the axle and at a degree to prevent wastage of the lubricant.It will further be Seen that by the use of my improved lnbricator, theusual form of Waste employed for retaining the lubricant may bedispensed with, and that-the lubricator may be quickly introduced intoor removed from engagement with the axle and further that the supply oflubricant may be readily replenished at any time. It will likewise beseen that the tension of the springs will not only force the lubricantthrough the slits in the wall 11, but that the pressure employed forfeeding the lubricant will also maintain the curved upper wall inengagement with the frictional surface of the channel 3.

What I claim is: A device of tl'i'e-character described, comprising alubricant holder formed of sections, a plunger arranged in the uppersection and resilient members arranged inter- CHARLEY ALLEN DOTSON;
